,State of., Ohio, have invented certain new and 'useful `Improvements in Filing-Cabinets; and I hereby declaresthe following to be a full," clear, and exact description of the "invention, such as will enable others skilled in the art to which it pertains to make and `use the same. y l 1 This invention relates toy improvements in filing cabinets more` especially designed for holding duplicates 4of bills or statements of account of any kind or slips or papers for reference` to enable a merchant or manufacturer to conveniently and readily ascertain any information relative to his customers accounts or other businessl without necessitating the use of regular-sets of .account The primary object of this invention is to provide a file of the 4character indicated which, in the embodiment herein illustrated andA described, comprises the following:-

acase adaptedrto y'be placed upon a desk,

table or stand and open at`.tl1e front; two

laterally spaced side plates. which'. are ar! ranged within and supported from the case ranged as )required to'vr renderythe leaves cay f pable ofvbeing swungfrom an'upright posiand instrumental. in supporting leaves for holding bills, slips or other papers which are to vbe filed away for ready reference, said leaves being normally arranged in an upright position in echelon, vthe one behindand -projecting above the other, between the supporting member; pivotal bearings for the leaves at` thelower ends thereof and artion forwardly and downwardly into a forwardlyf` projecting horizontal or prone position and -vice versa; andmeans whereby the actuation of the `forward and lower of'ad- .jacent leaves into itsdownwardly swung position results in the shifting of the rearward `andupper ofthe said leaves directly forward, so that the foremost upright leaf -will always occupy substantially the Vsame vertical plane. y

lAnother object is' to'` provide a simple,` ref' 4liable and durable construction whereby the leaves can be actuated from their upright into their forwardly projecting prone posil panying drawings.'V l Y In the said drawings, Figure 1 is a top plan of a'file embodying my invention, and in this figure the inclosing case is `shown in section,l and all ofthe leaves arefshownin TILING-GABrNET. f

acting to retain the'leaves in their upright and normal position and yet to causeveach leaf when in its downwardly swung prone` position to remain in the last-mentioned p0- sition until lifted far enoughto renderthe jsaid leaf subject to the action of the means acting as aforesaid toretain the leaves' in.

their upright position. y t Another object is to have the. leaves Csub-y Anotherobject is to provide simple means stantially ncorrespond in" dimensions and :to

so arrange'and assemble'the partsthat Ithe leaves, when they are all in-their1downy wardly swung and horizontal?. position wherein they 'project'in the main forwardly of the supporting side plates,rest one upon the other and are substantially flush at 'all 'of their edges and therefore collocated infa rectangular pack and conveniently shiftable together rearwardly into the space between thel said plates when thek latter' are `drawn from the case so as to` require theleast in the claims, and illustrated inthe 4aceomtheir upright and normal position Awithin the case. Fig. 2 is a section in detail' on line 2--2,`Fig. 1,-:looking rearwardly.' Fig: 3 is a front view vin section `:on line 3 3, F ig.` 1, and portions are'broken away and 'in section in Fig. 3, to more elearlyillustrate certain features of construction. Fig. 4 is a vertical sectionon line 4 4, Fig. 3. looking in the direction indicated by the arrow. Fig. 5 is a section ,largely corresponding` with Fig. 4, but in Fig. 5 three ofthe leaves are shown in their forwardly and downwardlyswune position. Fig. 6 is a section showing the leaves slid rearwardly between the side a bottom A2, a back A and a top A.

Within the case are two uprightly arranged and parallel laterally spaced lleafsupporting 'side plates B supported within but removable forwardly from the case A.

That is, the plates B are arranged parallel with and in suitable proximity to opposite side walls A respectively of the case A.

The plates B are braced apart and tiedtogether 1n any approved manner,

rear. ends of the plates adjacent the Vtop edges of t-he plates. The' bar D extends be- Y tween the plates B at the bottomnedges of the plates and near the forward ends of the plates. The bars D and D are secured te' thev plates B in any approved manner. Upward displacement of the plates B is prevented by bars d which overlap the top Y. -lflpper bar fthey overlap the forward side of the said 4' free to be removed forwardly from betweenv right position s wung of and are suitablysecured to edges of the plates and extend transversely the side walls A of the case. The plates B are removably secured to the case preferably by" two laterally spacedturn-buttons T swiveled or pivoted, as at t, to the rear wall A3 of the case and having-'such arrangement relative to the D that in their operative position bar. Obviously the plates B are. rendered the walls A upon turning the buttons T into their inoperative position relative to the bar D as shown in dotted lines'Fig. 2.

C represents the leaves which extend be- 'tween the plates B and are normally ar- 4.5 ranged face to face in' echelon one behind above the other in an upbetween the said laterally spaced plates. The leaves C substantially correspond inl dimensions and are pivotally supported at their lower ends and arranged 'as required to render them capable of being from their upright and normal position between the plates forwardly and downwardly .into a forwardly prone position, and vice versa.

bearings for preferably comprise pivotalscrews e with which the said leaf. is provided at opposite side edges respectively thereof, which pivetal screw-'sare arranged horizontally and in line endwise at the lower end of and screwed into the leaf and extend into the latter from within sliding blocks or slides E with which the plates B are provided. The pivotal members c of the different leaves C have and projecting The pivotal as, for in' stance, by two rods or bars D and D. The' bar D extends between the plates B at the.-

projecting the vlower end of each leaf C such relative'farrangement that the axes of vthe said leaves are spaced vertically as well as forwardly and rearwardly between'. the forward and rear ends ofV the plate B.

The pivotal members e are also arranged and supported as re uired to render the' rearward and upper o adjacent leaves 'slide able or shiftablehorizontally forward during the actuation. of the forward and lower of the said leavesinto its downwardly swung' prone position.

' Preferably each plateiB is provided at its inner side wit-h a -tier of vertically spaced recesses or slideways B2 which extend forwardly and rearwardly of the plate in a horizontal plane. The recesses B2 extend forwardly into suitable proximity to the forward extremity of the respective .plate B and have forward'end walls .b arranged -in line vertically. The recesses B?. extend rear- 'wardly into suitable proximity .to the rearv extremity of the respective plate B and have rear end` walls b arranged in linevert-ic-ally.

EachA recess or slideway B2 in each plate B4 s arranged in line laterally and corresponds in arrangement and dimensions with the corresponding. recess or slideway in the other plate B. Each ,screw or pivot e extends loosely through the respective sliding block E. Each leaf C and each ofthe slidvingblocksE into which the pivot-al bearings of the lsaid leaf extend are spaced laterally to accommodate the interposition be'- tween them of a washer f which exten'ds above land below the adjacent sliding block and thereby serves as a spacing member between they saidA block 4and the respective leaf,

as shown very clearly in Fig. 3.

Means are provided whereby actuation of eaclrof the forward and lower of adjacent leaves C int-O its downwardly swung prone position results in the shifting of the rearward and upper of the said leaves forward a distance equal to the-interval occufv pied by one of the uprighty leaves, which interval is preferably equal to the` extent of the projection of one leaf'above 'the other in their upright position in echelon. These means preferably comprise areal-ranged at opposite side edges `respectively of the forward and rlower of the said leaves and participate in the establishment of operative connect-ion between the said leaves, which links are pivoted, at one end, as at C2, to the lower of the said leaves between the axis and the free end of the said lower leaf ybut in suit-able proximity to and parallel with the said axis, said links being pivoted, at their other end, as at 13, to the sliding blocks engaged by the pivotal bearings e of the upper of the said leaves, rear wardly of and parallel with the said bearings.

Means for preventing rearward swinging links C which Y tion of the said leaf are provided and pref-"I" erablycomprise braces E which are formed "byupwardly projecting arms of the sliding sbloclrswliich bear t-he Apivotal bearings e of the said leaf. The said arms E" are ar-y 1f M:ifa,ngefdfat t-he rear ,side of the said leaf, and

. H'lipriaontally rearwardly in the upright and f nornial position of theleaves and its other arm Gr2 y'depending below the fulcrum of the d, projecting somewhat rearwardly "esition of theleaves. The deof each lever 'G is provided at` free endwith a laterally projefc H z member g2 engaged by a hook l: ch.. is, p`voted, as at h, horizontally an Iparallel-withthe axis of the'lever', to the uppermost leaf. ltwill be observed thereforethatthe, levers Gr are` operatively "but `detachably connected 'with' the uppermostlea'f.` Suitably `applied spiral springs I act to retain the levers Gr inposition hold-` "in the uppermost leaf against the braces `VE.s in..

the .uppermost leaf, which springs are atv,tachednatone end to the arms G of the levers and at their other end to the case A.

.j Y The bottom of the case A is provided with La' forward extension a which. has a raised iportion af', affording a bottom 'bearing to the lowermost leaf im the downwardly swung 40'"prone/position ofthe said leaf.

,Meansffor preventing rearward displacement yof the lowermostl leaf are provided and preferably comprise a bar a2 arranged transvei: ely of and suitably secured lto the 5 bottom f the case A,fand pins or projections lf, with which the sliding blocks to whic "thelowermost leaf is pivoted are proj vi d; The bai a2 extendsbetween the plates and is located in'rear of said pins or projection's It will be observed therefore that hef projection of tlieinembers 14 of the lastentioned' sliding blocks in front of the bai` coperate with the said bar in preventing f arward displacement of the said blocks '55 i nd connected lowermost leaf.4 It will also observed that because of the presence of e bar a2 the platesB, in removing the 1leaves from Within the case A, must be M withdrawn forwardly from the said case j preparatory to sliding the leaves rearwardly between the said plates, as shown in Fig. 6. By theconstruction hereinbefore described illbe observed that the relative arrangediiii'nsions and assemblage of the `the,revarvg'fardand' normal position ofl E that the' axes 'of adjacent leaves when the latter are in their downwardly swung prone position are arranged inline vertically and the said leaves are substantially flush at-all of theiredges and form a rectangularpaclr; that the attachment of springs directly to the" leaves' is avoided; that only two springs are required to retain all the leaves in their upright and normal position, and that these springs are attached to the caseA; that friction between the-leaves duringthe actuation of the leaves is avoided; that when the leaves are in their downwardly swung prone position onlyA the plates B need be released from the case A andthe hooks H disconnected from the levers Gr to render the said plates and connected* leaves free'to be removed from within theycase, and that when the 'plates B are removed from within the case A, as shown in Fig. 6, the leaves when 'the latter are. all

actuated into their downwardly swung posiition can be shoved rearwardly between the said-plates B, as illustratedin Fig. G, as desired preparatory to removing them to the safe in which the saidleaves are kept out of business-hours.'y I

The arrangement of the parts and tension of the springs and weight of the, leaves-are such th t any leaf, when it hasmoved rmore than hr lf way `during its actuation from its vertical and `normal into its downwardly swung prone position, will drop into the `last-mentioned position by gravity, and that the said leaf, when it has moved more than half way during its movement from its prone into its upright position, will be actuated into its upright position by'the springs.

Each leaf preferably consists in the main of a met-al sheet whichis providedat each t side thereof with laterally spaced *springclamps or members J for holding the papers to be filed against the sheet. The said leaf is bent at each side edge thereof, as at 1T, (see Figs. land 3) around a metal bar 18 which reinforces the sheet and affords a suitable member to which to attach. the pivotal screws e which, as already indicated, form the pivotal bearings of the leaves. The said leaf is also cut away vat its 'side edges,

at 20 as shown in the illustration of the lowermost leaf `in Fig. 3, .to accommodate the location and operation of the links C.

It is evident that the side plates, either with or without the case, and the sliding blocks, taken together, constitute a frame in `which the leaves are mounted, and that when thus consideredthelinks constitute a gearing-connection joining the respective leaves and blocks, whereby a rotation of the former slides the latter endwise; and it is also evident that the side plates, the sliding blocks and the links, collectively considered', con? stitutea gearing-connection joining the respective leaves, whereby the forward rota- 4tion of the leaves from" their normally upright position in echelon brings them into a prone position in a rectangular pack, and

vice versa, and in so doingall the upright j echelon between the said plates forwardly and downwardly into a forwardly projecting position in a rectangular pack, and vice 2.
